Lilly to sell cheaper version of top-selling insulin Humalog

INDIANAPOLIS — Eli Lilly is offering a half-price version of a top-selling insulin to ease the financial strain imposed on some patients, but an advocacy group says much bigger changes are needed.

The drugmaker said Monday it will introduce a version of the diabetes treatment Humalog that will be called Insulin Lispro and come with an initial price 50 percent lower than Humalog's current rate of about $275 per vial.
